In the whole process of woven fabric production, the cloth edge plays an extremely important role. Next, I will introduce the importance of woven fabric edge
1. In the weaving process, the cloth edge must be tightened at both ends of the weft yarn to bear the strength of the temple so that the cloth surface of the woven fabric will not produce excessive weft shrinkage. In addition, the selvage also has the functions of reducing the warp warp at the side, improving the friction of the warp at the side and the reed teeth, reducing the rate of breakage of the warp at the side, increasing the strength of the side, keeping the cloth surface flat and having the same width. It is easier to make the whole winding into shape, which is convenient for the processing of subsequent procedures.
2. In the process of dyeing and finishing, the edge of the woven fabric is also subject to the tension of the cloth clip or needle punching, especially the cellulose fiber fabrics such as cotton and linen. It has to withstand a lot of tension during the finalizing and tentering process after mercerizing. After all, a firm, smooth, and properly elastic side structure is a necessary condition for finishing. If the edge design of the woven fabric is unreasonable, the fabric will have loose edges, broken edges, tight edges, curled edges, etc., and a lot of broken edges will occur, and even the finishing process will not be carried out at all. Cause huge losses.
Considerations when making woven fabric edges
1. Width. The side weave is too narrow, the strength is not enough, can not withstand the tension, it is easy to tear the side, can not provide protection; the side weave is too wide, increase the cost of the fabric, under the condition of a certain width will affect the fabric can be cut area. Generally speaking, simply weave the fabric with a smaller width, but the edge width of some same-side, different-side weaves and elastic fabrics with longer floating lengths should be appropriately increased according to the situation.
2. Thickness. The edge thickness of the woven fabric should be as consistent as the body of the woven fabric, so that it is easy to keep the fabric flat, wound, beautiful and evenly stressed.
